I like to carry a handgun while bow hunting and since it came out it is usually the pmr 30. 2 mag 60 rnds total light weight "great survival tool. If I hunted in big bear country with a I would still carry the pmr but I would add something like a 4' 8 shot revolver 357 mag air weight of course, Heavy for caliber hard cast lead bullets. If i was in a known problem bear area with a bow instead of a rifle the revolver may turn into a short barrel 12 ga. with number 1 buck in a 3" shells. I don't want to carry a giant hand cannon when there is a no to very low chance of an encounter. If I had to pick a handgun to shoot a determined charging large bear it would most likely be a long heavy barreled shroud, muzzle brake. Steel "no air weights" 500 s&w with heavy hard cast lead, that way at least if you missed the CNS your hits would still do life ending damage or skeletal structure damage. Not to mention the deafening, eye brow torching muzzle blast. Of course I would want to shorten the hand gun barrels to 2" when the bear got to hand to claw fighting distance. No matter what gun you pick at least your in the fight and are able to be proactive in your survival, that ability to defend give the mind and body a task to prevent the feeling of helplessness and panic that one would have with no weapon. Just my thoughts and choices.
